In almost every kitchen in this present time, water filtration systems are a common fixture. This is because many scientists and heath experts have warned on the pollutants found in our drinking water supply. These pollutants are manmade found not just at home but in municipal systems, glaciers, rivers, lakes and wells. It is known to come with its own issues that have severe health and environmental impacts. Installing a good water filtration system is the safest way to make sure that water is safe and drinkable. This, however, doesn’t end at just installing filters.
PUR Water Filter differ as well as their costs and how effective they can be even though the overall purpose is for safe and quality drinkable water. When thinking about kitchen renovation it is also of equal timing to think about the available choices in selecting filters. For selecting the best water filter, some of the much-known filters are discussed below.

Reverse Osmosis

One of the best available filtration techniques in the present day is the reverse osmosis. This is a very old process which has lasted for more than a century. It was only in the 1950s that the United States built it up as a system the Marines can use to make water drinkable by desalinating it. Normal osmosis is when there is a movement of molecules through a membrane to balance the concentration of molecules on either side. Reverse osmosis is the reverse of the normal osmosis process. Rather than balancing the concentration of molecules on either side of the membrane, water pressure carries clean water one side of the membrane. On the other side, a concentration of pollutants is left. Reverse osmosis usually makes use of two carbon filters as well as other pre-filters that help to wipe contaminants.

Some of these contaminants are arsenic, mercury and lead. By reverse osmosis, there is an effective removal of medications. Some are MTBEs, THMs, viruses, VOCs, pesticides, herbicides, chloramines, fluoride, chlorine, percolate, coliform bacteria, E.coli and Cryptosporidium. There are usual countertop or faucet filters classified as one stage filter because of their single basic carbon filter. But in comparison, the reverse osmosis system offers a five-stage filtration system. In addition, countertop filters contaminate less than one micron. Thus insecticides and asbestos might not be filtered out. This gives it a 1-5 micron rating. On the other hand, with reverse osmosis filter, it usually has a .0001 micron rating. Though at the initial stage reverse osmosis can be quite more expensive, replacing the filter is done once in 12 months. Replacing countertop filters, on the other hand, is done every few months.
Effective reverse osmosis gets rid of a striking collection of harmful contaminants. At the same time, it can also get rid of essential minerals that improve taste and health of the water.

This includes potassium, magnesium and calcium. Some researchers could argue that regular foods have these minerals in them and thus its presence in drinking water is not necessarily needed. Other health experts, however, would stress on the long-term health impact of water that has been demineralized. This health impacts, they suggest being a harmful level of acidity and mineral deficiency. Furthermore, for one gallon of pure water, reverse osmosis would require about two or three gallons of water. This again some professionals consider as being uneconomical.

Other Well-Known Filters

There are some other well-known filters.

Water pitcher filter is one of them.

It is easy to use.

It can minimise chlorine by-products, chlorine copper and lead.

Notwithstanding, it is better to have any filter than not to have at all.

Pitcher filters for their price are perhaps the least efficient filters bearing in mind that it still has to be replaced every couple of months. Some of these pitcher filters are quite slow and tend to clog. Because its life span is short, it is not recommended for a big family that can consume plenty gallons of water.

Another one is the Filter faucets or the direct installation of filters on faucets. It is also well-known and just like the pitchers are easy to use. Being placed on the head of a faucet, a person can easily switch to filtered or unfiltered water. Most of them are efficient in getting rid of chlorine, lead, sediments and pesticides. Notwithstanding, as it is similar to the pitcher, it is usually slow and needs replacing regularly.

It is directly hooked to the faucet after removal of the aerator. The level of filtration for countertop is higher than that of a faucet or water pitcher because it uses in tandem carbon filters and other filters. This means that they are less prone to clog compared to the faucet or water pitcher. In addition, they give room for the filtration of a higher volume of water thus eliminating the need for the alteration of any plumbing. The under sink filter is comparable to the countertop in that it allows a high volume of water to be filtered. However, dissimilar to the countertop, it doesn’t use up valuable counter space. It rather is attached to pipes under the sink. Its two-step filtering procedure makes it more efficient than pitchers. It, however, requires adjustments to the plumbing by an expert.
